进一步地，参照图1至图3B，所述潜望式摄像模组100包括一镜头单元30，其中所述镜头单元30被设置于所述光处理单元10和所述感光元件20之间，且所述镜头单元30被保持于所述感光元件20的感光路径，从所述光处理单元10射出的多束所述单色光300到达所述镜头单元30，且所述单色光300被所述镜头单元30聚焦，进一步地，经过所述镜头单元30后的不同颜色的所述单色光300分别成像于所述感光元件20的所述感光面210，以获得多个不同清晰物面位置的成像。由于不同颜色的光在同一介质中的折射率不同、传播速度也不相同等因素的影响，与所述潜望式摄像模组的所述感光元件20的所述感光面210距离相同的物面所反射进入所述潜望式摄像模组内的所述复合光400被分散形成的所述红色光、所述绿色光以及所述蓝色光会被聚焦于不同的平面，即，不同颜色的所述单色光300能够形成的清晰的像面位置也不一致，利用算法将不同清晰物面位置的图像合成后得到所述潜望式摄像模组的最终图像，进而提升了所述潜望式摄像模组100的景深。
具体来说，参照图3A和图3B，所述复合光400经过所述光处理单元10后 发生色散形成所述单色光300，由于不同的所述单色光300的波长和频率不同，且所述光处理单元10对具有不同波长的所述单色光300的折射率不同，使得不同的所述单色光300从所述光处理单元10射出后的位置也不相同。比如说，沿X轴方向传播的所述复合光400经过所述光处理单元10后形成的沿Z轴方向传播的所述单色光300按照所述红色光、所述橙色光、所述黄色光、所述绿色光、所述蓝色光、所述靛色光以及所述紫色光的顺序依次自上而下排列，即，当七种颜色的所述单色光300到达垂直于Z轴方向的平面，如，所述感光元件20的所述感光面210，不同颜色的单色光300形成的图像区域也自上而下排列于所述感光元件20的所述感光面210，其中所述红色光位于最上方的区域，所述橙色光次之，所述紫色光位于最下方的区域，进而提升了不同清晰物面的离散程度，以利于所述潜望式摄像模组100通过将不同单色光300的成像叠加的方式实现提升景深。在本发明的一较佳实施例中，所述光处理单元10为一棱镜。本领域技术人员应该知晓的是，所述光处理单元10的具体实施方式仅仅作为示例，不能成为对本发明所述潜望式摄像模组100的内容和范围的限制。
进一步地，所述感光元件20对应地接收不同颜色的所述单色光300，所述感光元件20将光信号转换成电信号，并将电信号传输至与所述感光元件20可通信地连接的一处理装置50，进而能够分别得到不同颜色的所述单色光的图像，即，获得多个不同清晰物面位置的成像。通过算法将不同颜色的单色光的图像进行叠加后合成所述第一图像101。
优选地，所述感光元件20的所述感光面210对应地接收所述红色光、所述绿色光以及所述蓝色光这三种颜色的所述单色光300，进而得到所述红色光、所述绿色光以及所述蓝色光单独的清晰的成像，即，获得三个不同清晰物面位置的成像。所述红色光的图像、所述绿色光的图像以及所述蓝色光的图像对应于三个不同清晰物面位置，根据算法合成所述红色光的图像、所述绿色光的图像以及所述蓝色光的图像，以实现提升景深。比如说，参照图3A，所述感光元件20的所述感光面210对应地接收所述红色光、所述绿色光以及所述蓝色光这三种颜色的所述单色光300，进而分别得到所述红色光的成像A、所述绿色光图像B以及所述蓝色光的图像C，其中所述红色光的成像A、所述绿色光图像B以及所述蓝色光的图像C相当于三个不同清晰物面位置的成像，根据所述红色光的成像A和所述绿色光的图像B以及所述蓝色光的图像C的信息能够获得被拍摄物体的物面位 置A’、物面位置B’以及物面位置C’，从而在后续，根据算法能够获得合成所述红色光的成像A、所述绿色光图像B以及所述蓝色光的图像C，以得到所述被拍摄物体的清晰图像。应该理解的是，所述感光元件20也可以通过接收其他颜色的所述单色光300获得被拍摄物体的图像。
具体来说，参照图2B，所述感光元件20的所述感光面210包括多像素点21，即，所述感光元件20的所述感光面210包括一像素点阵列，并藉由多个所述像素点21接收对应的所述红色光、所述绿色光以及所述蓝色光，进而能够得到三种颜色的所述单色光300的清晰的图像。也就是说，所述感光元件20的所述红色像素单元2111、所述绿色像素单元2112、以及所述蓝色像素单元2113对应的所述红色光、所述绿色光以及所述蓝色光的成像相当于是三个不同清晰物面位置的光学系统，通过算法将不同清晰物面位置的“三摄”的图像合成后，能够得到被拍摄物体的最终图像。应该理解的是，“三摄”的图像是指通过藉由所述红色像素单元2111、所述绿色像素单元2112、以及所述蓝色像素单元2113所得到的所述红色光的成像、所述绿色光的成像以及所述蓝色光的成像。
更具体地，所述像素点21包括多个所述像素单元211，其中每个像素单元211能够接收对应颜色的所述单色光300，多个所述像素单元211有序地自上而下排列，进而使得所述像素点211能够接收对应颜色的所述单色光300。所述像素单元211选自：一红色像素单元2111、一绿色像素单元2112、以及一蓝色像素单元2113组成的像素单元类型中的一种或是多种的组合，其中所述红色像素单元2111能够接收所述红色光，所述绿色像素单元2112能够接收所述绿色光，所述蓝色像素单元2113能够接收所述蓝色光，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113被按照一预设规则排列，进而使得所述像素点21能够接收对应颜色的所述单色光300。在说明书附图和下面的描述中，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113分别用字母“R”、“G”以及“B”代表，如图2B所示。
优选地，所述感光元件20被实施为不规则颜色滤光器阵列。具体来说，所述像素单元211按照R-RB-RGB-RG-G的顺序自上而下地排列，使得所述感光元件20能够接收对应颜色的所述单色光。具体来说，由于不同的所述单色光300的波长和频率不同，且所述光处理单元10对具有不同波长的所述单色光300的折射率不同，使得不同的所述单色光300从所述光处理单元10射出后的位置也不 相同，且所述单色光300按照所述红色光、所述橙色光、所述黄色光、所述绿色光、所述蓝色光、所述靛色光以及所述紫色光的顺序依次自上而下排列，因此，对应的仅包含所述红色像素单元2111的所述像素单元211分布于最上方，仅包含所述蓝色像素单元2113的所述像素单元211分布于最下方。进一步地，由于折射角度和焦距的影响，所述红色光、所述绿色光以及所述蓝色光难以完全分离，即，自上而下会出现所述红色光和所述绿色光重合，所述红色光、所述绿色光和所述蓝色光，所述绿色光和所述蓝色光重合的现象，对应地，包括至少一个所述红色像素单元2111和至少一个所述绿色像素单元2112的所述像素单元211位于仅包含所述红色像素单元2111的所述像素单元211的下方，包括至少一个所述红色像素单元2111、至少一个所述绿色像素单元2112以及至少一个所述蓝色像素单元2113的所述像素单元211位于仅包括所述蓝色像素单元2113的所述像素单元211的上方。也就是说，按照色散后形成的所述单色光300的分布设计对应的所述感光元件20的所述像素点21的所述像素单元211，使得所述感光元件20能够更好地接收对应颜色的所述单色光300，进一步有利于提升成像效果。
可选地，所述感光元件20被实施为RGB颜色滤光器阵列，即每个所述像素单元211包括至少一个所述红色像素单元2111、至少一个所述绿色像素单元2112以及至少一个所述蓝色像素单元2113。
可选地，所述感光元件20被实施为RGBW颜色滤光器阵列，其中“W”为一白像素单元，即，每个所述像素单元211包括至少一个所述红色像素单元2111、至少一个所述绿色像素单元2112、至少一个所述蓝色像素单元2113以及至少一个白色像素单元，通过所述白像素单元来补充亮度，以提高成像质量。
参照图1和图2A，所述潜望式摄像模组100进一步包括一滤色元件40，其中所述滤色元件40被保持于所述感光元件20的感光路径，且所述滤色元件40被设置于所述感光元件20前，使得进入所述潜望式摄像模组100的光线先经过所述滤色元件40后再到达所述感光元件20。所述滤色元件40对杂光进行过滤，以保障形成于所述感光元件20的所述感光面210的成像的清晰程度。比如说，比如说，所述滤色元件40仅允许一预设波段的光线通过，以保障所述红色光、所述绿色光以及所述蓝色光分别形成清晰的独立的图像于所述感光元件20的所述感光面210，从而保障成像质量。优选地，所述滤色元件40被设置于所述镜头单元30和所述感光元件20之间，光线经过所述镜头单元30后到达所述滤色 元件40，所述滤色元件40对杂光进行过滤。优选地，所述滤色元件40被设置于所述镜头单元30和所述光处理模块10之间。应该理解的是，所述滤色元件40的具体实施方式仅仅作为示例，不能成为对本发明所述潜望式摄像模组100的内容及范围的限制。
在说明书附图4所示出的所述潜望式摄像模组100的这个具体的实施例中，所述潜望式摄像模组100进一步包括一辅助元件80，其中所述辅助元件80被设置于所述光处理单元10和所述镜头单元30之间，且所述辅助元件80被保持于所述感光元件20的感光路径，从所述光处理单元10射出的所述单色光300经过所述辅助元件80后被分散，使不同颜色的所述单色光300的重叠部分被减少，这样，所述红色光、所述绿色光以及所述蓝色光的重叠区域被减少，以利于所述感光元件20更好地接收对应颜色的所述单色光300，并提高了所述红色光、所述绿色光以及所述蓝色光单独形成的图像的清晰度，所述辅助元件80可进一步提升景深。优选地，所述辅助元件80被实施为一柱面镜。优选地，所述辅助元件80被实施为一自由曲面。
说明书附图5中示出的所述潜望式摄像模组100与附图2A中示出的所述潜望式摄像模组100的差异在于，图5中示出的所述潜望式摄像模组100进一步包括一驱动元件90，其中所述光处理单元10被可驱动以转动地连接于所述驱动元件90，使得从所述光处理单元10射出的所述红色光、所述绿色光以及所述蓝色光能够全部被所述感光元件20接收，通过这样的方式，使得所述感光元件20不需要扩大所述感光元件20的所述感光面210的面积就能够接收全部的所述红色光、所述绿色光以及所述蓝色光。举例来说，由于所述光处理单元10对不同的颜色的所述单色光300的折射率不同，从所述光处理单元10射出的所述单色光300与YZ平面所成的角度不同，随着光的传播，所述单色光300之间的距离会变大，若要接收全部的所述红色光、所述绿色光以及所述蓝色光，需要的所述感光元件20的感光面积偏大，不利于所述潜望式摄像模组100轻薄化，而通过驱动所述光处理单元10绕Y轴转动，使得所述感光元件20能够依次接收所述红色光、所述绿色光以及所述蓝色光，并分别得到三种颜色的所述单色光300对应的图像，以在后续能够得到所述第一图像101。
依本发明的另一个方面，本发明进一步提供一潜望式摄像模组的图像获取方法，其中所述图像获取方法包括如下步骤：
(a)藉由一光处理单元10转折来自一被拍摄物体的一复合光400的同时分散所述复合光400，形成多束单色光300；
(b)藉由一感光元件20的一感光面210接收所述单色光300，分别获得不同颜色的所述单色光300的成像；以及
(c)合成不同颜色的所述单色光200的成像，以得到被拍摄物体的最终图像。
具体来说，在所述步骤(a)中，来自被拍摄物体的所述复合光400经过所述光处理单元10能够发生色散，进而形成不同颜色的所述单色光300，即，所述复合光400经过所述光处理单元10后发生色散形成所述红色光、一橙色光、一黄色光、所述绿色光、所述蓝色光、一靛色光以及一紫色光七种颜色的所述单色光300，并在后续，不同颜色的所述单色光300能够成像于所述感光元件20的所述感光面210，其中不同颜色的所述单色光300对应所述被拍摄物体不同清晰物面位置，具体地，每一所述单色光300的清晰的成像对应于被拍摄物体的一个清晰物面位置，并在后续，通过算法将不同颜色的所述单色光300的清晰成像相互叠加，以合成所述被拍摄物体的最终图像，通过这样的方式提升了所述潜望式摄像模组100的景深。
优选地，在所述步骤(b)中，所述感光元件20的所述感光面210对应地接收所述红色光、所述绿色光以及所述蓝色光，进而获得所述红色光、所述绿色光以及所述蓝色光的清晰的成像。值得一提的是，所述感光元件20接收的所述单色光300的具体颜色不能成为对本发明所述潜望式摄像模组的图像获取方法的内容和范围的限制。更具体地，藉由所述感光元件210的所述感光面210的所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113分别地接收所述红色光、所述绿色光以及所述蓝色光，进而分别获得所述红色光、所述绿色光以及所述蓝色光的成像。更优选地，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113按照R-RB-RGB-RG-G的顺序自上而下地排列的方式对应地接收所述红色光、所述绿色光以及所述蓝色光。
在所述步骤(b)之前进一步包括步骤(e)：藉由一镜头单元30汇聚所述单色光300。
优选地，在所述步骤(e)之后进一步包括步骤(f)：藉由一辅助元件80扩大不同颜色的所述单色光300之间的距离。具体来说，从所述光处理单元10射 出的所述单色光300经过所述辅助元件80后被分散，使不同颜色的所述单色光300的重叠部分被减少，这样，所述红色光、所述绿色光以及所述蓝色光的重叠区域被减少，以利于所述感光元件20更好地接收对应颜色的所述单色光300，并提高了所述红色光、所述绿色光以及所述蓝色光单独形成的图像的清晰度。
在所述步骤(b)之前进一步包括步骤(g)：藉由一滤色元件40过滤杂光。具体地，所述滤色元件40仅允许一预设波段的光线通过，以保障所述红色光、所述绿色光以及所述蓝色光分别形成清晰的独立的图像于所述感光元件20的所述感光面210，从而保障成像质量。
优选地，在所述步骤(b)之前进一步包括步骤(h)：转动所述光处理单元10。具体来说，藉由一驱动元件90够驱动所述光处理单元10转动，使得所述感光元件20能够依次接收所述红色光、所述绿色光以及所述蓝色光，通过这样的方式，能够使得从所述光处理单元20射出的所述红色光、所述绿色光以及所述蓝色光能够全部被所述感光元件20接收，利于所述潜望式摄像模组100轻薄化。
根据本发明的另一个方面，依本发明的另一较佳实施例的一潜望式摄像模组100将在接下来的描述中被阐述。参照说明书附图6和图7，至少一所述潜望式摄像模组100被应用一摄像模组1000，其中所述摄像模组1000能够获得高质量的图像。具体来说，所述摄像模组1000包括至少一所述潜望式摄像模组100和至少一主摄像模组200，其中所述潜望式摄像模组100和所述主摄像模组200能够分别获得一第一图像101和一第二图像102，其中所述第一图像101和所述第二图像102通过算法能够合成所述摄像模组1000的一最终图像103。进一步地，所述潜望式摄像模组100能够确定实际景物的位置，并获得实际景物的轮廓，且所述潜望式摄像模组100获得的所述第一图像101具有深度信息，通过所述第一图像101和所述第二图像102融合得到的所述最终图像103能够体现出实际景物的轮廓，并呈现出立体的效果，进而提高了所述摄像模组1000获取的图像质量。
值得一提的是，所述摄像模组1000的所述潜望式摄像模组100和所述主摄像模组200的数量不受限制，比如说，所述摄像模组1000可以被实施为双摄模组，即，所述摄像模组1000包括一个所述潜望式摄像模组100和一个所述主摄像模组200；所述摄像模组1000也可以被实施为三摄模组，即，所述摄像模组1000包括两个所述潜望式摄像模组100和一个所述主摄像模组200，或是，所述摄像模组1000包括一个所述潜望式摄像模组100和两个所述主摄像模组200。 所述摄像模组1000的所述潜望式摄像模组100和所述主摄像模组200的具体数量仅仅作为示例，不能成为对本发明所述摄像模组1000及其所述潜望式摄像模组100的内容及范围的限制。在本发明的说明书附图及下面的描述中，以所述摄像模组1000被实施为双摄模组为例。
参照图1至图3B，所述潜望式摄像模组100通过接收一单色光300的方式成像，并根据接收的所述单色光300的锐利程度分析实际景物的实际位置，并获得实际景物的轮廓。具体来说，所述潜望式摄像模组100包括一光处理单元10和一感光元件20，其中所述光处理单元10被保持于所述感光元件20的感光路径，进入所述潜望式摄像模组100的光线能够经过所述光处理单元10后能够到达所述感光元件20，并成像于所述感光元件20的一感光面210。进一步地，外部环境中的一复合光400经过所述光处理单元10发生色散，进而形成所述单色光300，即，所述复合光400经过所述光处理单元10后发生色散形成一红色光、一橙色光、一黄色光、一绿色光、一蓝色光、一靛色光以及一紫色光七种颜色的所述单色光300，并在后续，所述红色光、所述绿色光以及所述蓝色光这三种颜色的所述单色光300能够成像于所述感光元件20，进而根据这三种颜色的所述单色光300形成的图像分析计算每个所述单色光300对应的实际景物的位置，从而得到实际景物的轮廓。具体来说，所述感光元件20的所述感光面210为一平面，由于所述红色光、所述绿色光和所述蓝色光，对应折射率不一致、传播速度等存在一定差异，且所述红色光、所述绿色光以及所述蓝色光对应的实际景物的位置和所述感光元件20的所述感光面210之间的相对位置也存在差异，因此，藉由所述感光元件20接收到的不同单色光的锐利程度也存在差异。进一步地，根据形成于所述感光元件20的所述感光面210的图像，能够分析出不同单色光对应的实际景物位置或者深度信息。应该知晓的是，外部环境中的白光、太阳光等都属于所述复合光400。
值得一提的是，所述光处理单元10能够改变经过进入所述潜望式摄像模组100的光束的光路方向。比如说，沿着X轴方向传播的所述复合光400入射至所述光处理单元10，经过所述光处理单元10后能够沿着Z轴方向传播，即，藉由所述光处理单元10能够使得进入所述潜望式摄像模组100的光束的光路发生转折，进而所述潜望式摄像模组100在具有长焦拍摄效果的同时能够降低所述摄像模组1000的整体高度，以利于所述摄像模组1000被应用于一移动电子设备2000， 并符合所述移动电子设备2000轻薄化发展的趋势，其中所述移动电子设备2000如手机、iPad等。
参照图3A和图3B，所述复合光400经过所述光处理单元10后发生色散形成所述单色光300，由于不同的所述单色光300的波长和频率不同，且所述光处理单元10对具有不同波长的所述单色光300的折射率不同，使得不同的所述单色光300从所述光处理单元10射出后的位置也不相同。比如说，沿X轴方向传播的所述复合光400经过所述光处理单元10后形成的沿Z轴方向传播的所述单色光300按照所述红色光、所述橙色光、所述黄色光、所述绿色光、所述蓝色光、所述靛色光以及所述紫色光的顺序依次自上而下排列，即，当七种颜色的所述单色光300到达垂直于Z轴方向的平面，如，所述感光元件20的所述感光面210，不同颜色的单色光300形成的图像区域也自上而下排列于所述感光元件20的所述感光面210，其中所述红色光位于最上方的区域，所述橙色光次之，所述紫色光位于最下方的区域。在本发明的一较佳实施例中，所述光处理单元10为一棱镜。本领域技术人员应该知晓的是，所述光处理单元10的具体实施方式仅仅作为示例，不能成为对本发明所述潜望式摄像模组1000的内容和范围的限制。
进一步地，参照图1和图2A，所述潜望式摄像模组100包括一镜头单元30，其中所述镜头单元30被设置于所述光处理单元10和所述感光元件20之间，且所述镜头单元30被保持于所述感光元件20的感光路径，从所述光处理单元10射出的所述单色光300能够到达所述镜头单元30，且所述单色光300能够被所述镜头单元30聚焦，进一步地，经过所述镜头单元30后的所述红色光、所述绿色光以及所述蓝色光这三种颜色的所述单色光300能够成像于所述感光元件20的所述感光面210。
参照图1和图2A，所述潜望式摄像模组100进一步包括一滤色元件40，其中所述滤色元件40被保持于所述感光元件20的感光路径，且所述滤色元件40被设置于所述感光元件20前，使得进入所述潜望式摄像模组100的光线先经过所述滤色元件40后再到达所述感光元件20。所述滤色元件40对不同颜色的所述单色光300进行过滤，仅允许所述红色光、所述绿色光以及所述蓝色光通过，保障仅所述红色光、所述绿色光以及所述蓝色光能够成像于所述感光元件20的所述感光面210，从而保障成像质量。进一步地，三种颜色的所述单色光300对应的实际景物的位置存在差异，分析三种颜色的所述单色光300形成于所述感光 元件20的所述感光面210的像，能够获得分析实际景物的位置或深度信息，并获取实际景物的轮廓。
具体来说，所述红色光、所述绿色光以及所述蓝色光的折射率、传播速度等光学性质不一样，由实际景物上的同一个点，或是位于同一垂直平面内的点，即，与所述潜望式摄像模组的所述感光元件20的所述感光面210距离相同的点所反射进入所述潜望式摄像模组内的所述复合光400被分散形成的所述红色光、所述绿色光以及所述蓝色光会被聚焦于不同的平面，当所述感光元件20的所述感光面210的位置固定不变时，所述感光元件20的所述感光面210接收到的不同颜色的所述单色光300的锐利程度不相同。比如说，实际景物的上的同一位置反射进入所述潜望式摄像模组的复合光400分散形成的所述红色光形成于所述感光元件20的所述感光面210的像的锐利程度大于由所述复合光400分散形成的所述蓝色光于所述感光元件20的所述感光面210的成像。同样的，由所述感光元件20的所述感光面210接收的具有相同锐利程度的不同颜色的所述单色光300对应的实际景物的上的各个点位置也会不相同。比如说，所述红色光和所述蓝色光于所述感光元件20的所述感光面210的成像具有相同的锐利程度，对应的所述红色光对应的实际景物上的点与所述潜望式摄像模组的距离大于所述蓝色光对应的实际景物上的点与所述潜望式摄像模组的距离。进一步地，通过所述滤色元件40过滤杂光的方式保障了所述红色光、所述绿色光以及所述蓝色光于所述感光元件20的所述感光面210成像的清晰度，并减少了其他颜色的所述单色光300对获取实际景物所在位置的干扰，以利于提高所述潜望式摄像模组获取实际景物所在位置的准确性，以在后续能够更好地呈现出实际景物的轮廓。应该理解的是，本发明所述的杂光是指除了红色光、绿色光以及蓝色光以外的其他颜色的所述单色光300。
优选地，所述滤色元件40被设置于所述镜头单元30和所述感光元件20之间，且所述滤色元件40对从所述镜头单元30射出的所述单色光300进行过滤，使得仅所述红色光、所述绿色光以及所述蓝色光能够到达所述感光元件20，并在后续能够得到所述第一图像101。优选地，所述滤色元件40被设置于所述镜头单元30和所述光处理模块10之间，使得自所述光处理单元10射出的所述单色光300能够被所述滤色元件40过滤，进而仅所述红色光、所述绿色光以及所述蓝色光能够被所述镜头单元30聚焦。
进一步地，所述感光元件20对应地接收所述红色光、所述绿色光以及所述蓝色光三种颜色的所述单色光300，所述感光元件20将光信号转换成电信号，并将电信号传输至与所述感光元件20可通信地连接的一处理装置50，进而能够分别得到所述红色光的图像、所述绿色光的图像以及所述蓝色光的图像，并在后续通过所述处理装置50对所述红色光的图像、所述绿色光的图像以及所述蓝色光的图像进行分析，根据三种颜色的所述单色光300的锐利程度的差别得到实际景物所在的位置，以获得实际景物的轮廓。应该理解的是，所述红色光的图像、所述绿色光的图像以及所述蓝色光的图像能够被合成所述第一图像101。值得一提的是，所述处理装置50可以被实施为所述移动电子设备2000的处理器，且所述处理装置50也可以被实施为所述摄像模组1000自带的处理器，本领域技术人员应该理解的是，所述处理装置50的具体实施方式仅仅作为示例，不能成为对本发明所述的摄像模组1000和所述潜望式摄像模组100的内容和范围的限制。
具体来说，参照图2B，所述感光元件20的所述感光面210包括多像素点21，即，所述感光元件20的所述感光面210包括一像素点阵列，并藉由多个所述像素点21接收对应的所述红色光、所述绿色光以及所述蓝色光，进而能够得到三种颜色的所述单色光300对应的图像。更具体地，所述像素点21包括多个所述像素单元211，其中每个像素单元211能够接收对应颜色的所述单色光300，多个所述像素单元211有序地自上而下排列，进而使得所述像素点211能够接收对应颜色的所述单色光300。所述像素单元211选自：一红色像素单元2111、一绿色像素单元2112、以及一蓝色像素单元2113组成的像素单元类型中的一种或是多种的组合，其中所述红色像素单元2111能够接收所述红色光，所述绿色像素单元2112能够接收绿色光，所述蓝色像素单元2113能够接收所述蓝色光，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113被按照一预设规则排列，进而使得所述像素点21能够接收对应颜色的所述单色光300。在说明书附图和下面的描述中，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113分别用字母“R”、“G”以及“B”代表，如图2B所示。
优选地，所述感光元件20被实施为不规则颜色滤光器阵列。具体来说，所述像素单元211按照R-RB-RGB-RG-G的顺序自上而下地排列，使得所述感光元件20能够接收对应颜色的所述单色光。具体来说，由于不同的所述单色光300的 波长和频率不同，且所述光处理单元10对具有不同波长的所述单色光300的折射率不同，使得不同的所述单色光300从所述光处理单元10射出后的位置也不相同，且所述单色光300按照所述红色光、所述橙色光、所述黄色光、所述绿色光、所述蓝色光、所述靛色光以及所述紫色光的顺序依次自上而下排列，因此，对应的仅包含所述红色像素单元2111的所述像素单元211分布于最上方，仅包含所述蓝色像素单元2113的所述像素单元211分布于最下方。进一步地，由于折射角度和焦距的影响，所述红色光、所述绿色光以及所述蓝色光难以完全分离，即，自上而下会出现所述红色光和所述绿色光重合，所述红色光、所述绿色光和所述蓝色光，所述绿色光和所述蓝色光重合的现象，对应地，包括至少一个所述红色像素单元2111和至少一个所述绿色像素单元2112的所述像素单元211位于仅包含所述红色像素单元2111的所述像素单元211的下方，包括至少一个所述红色像素单元2111、至少一个所述绿色像素单元2112以及至少一个所述蓝色像素单元2113的所述像素单元211位于仅包括所述蓝色像素单元2113的所述像素单元211的上方。也就是说，按照色散后形成的所述单色光300的分布设计对应的所述感光元件20的所述像素点21的所述像素单元211，使得所述感光元件20能够更好地接收对应颜色的所述单色光300，进一步有利于提升成像效果。
可选地，所述感光元件20被实施为RGB颜色滤光器阵列，即每个所述像素单元211包括至少一个所述红色像素单元2111、至少一个所述绿色像素单元2112以及至少一个所述蓝色像素单元2113。
值得一提的是，所述感光元件20的所述感光面210为一平整平面，且所述感光元件20的位置是固定的，即像面是固定的，当所述感光元件20被设置于一预设范围内时，且所述红色光、所述绿色光以及所述蓝色光都能够成像于所述感光元件10的感光面。由于构成实际景物的轮廓的各个点与所述潜望式摄像模组100的之间的距离不同，且不同颜色的所述单色光300对应的实际景物的位置也不一样，所述感光元件20接收的不同颜色的所述单色光300的锐利程度也不相同。举例来说，参照图3A和图3B，所述感光元件20能够被设置于一A平面和一C平面之间的任意位置，并且所述实际景物对应的像面能够形成于所述感光元件20，一束所述红色光能够被聚焦的点位于所述平面B，则当所述感光元件10被设置于所述平面B对应的位置时，所述红色光形成于所述感光元件10的像的亮度较高，即，所述红色光的锐利程度较高，当所述感光元件20被设置于所述 B平面之前的所述C平面或是所述B平面之后的所述A平面，所述感光元件20能够接收到的所述红色光的亮度降低；同样的，另一束所述红色光能够被聚焦的点位于所述平面C，则当所述感光元件10被设置于所述平面C对应的位置时，所述红色光形成于所述感光元件10的像的亮度较高，即，所述红色光的锐利程度较高，当所述感光元件20被设置于所述C平面之后得所述B平面，所述感光元件20能够接收到的所述红色光的亮度降低，当所述感光元件20被设置于所述B平面之后得所述A平面，所述感光元件20能够接收到的所述红色光的亮度更低。应该理解的是，同一所述复合光400发生色散后形成的不同颜色的所述单色光300能够被聚焦的位置也不相同。换句话说，不同颜色的所述单色光300的光学性质不一样，由实际景物上的同一个点，或是位于同一垂直平面内的点，即，距离所述潜望式摄像模组的所述感光元件20的所述感光面210距离相同的点所反射进入所述潜望式摄像模组内的所述复合光400被分散形成的所述红色光、所述绿色光以及所述蓝色光会被聚焦于不同的平面，当所述感光元件20的所述感光面210的位置固定不变时，所述感光元件20的所述感光面210接收到的不同颜色的所述单色光300的锐利程度不相同；同样的，由所述感光元件20的所述感光面210接收的具有相同锐利程度的不同颜色的所述单色光300对应的实际景物的上的各个点位置也会不相同。也就是说，所述潜望式摄像模组通过将进入所述摄像模组的复合光分散成不同颜色的所述单色光300，并藉由所述感光元件20的所述感光面210接收所述单色光300的方式有利于根据不同颜色的所述单色光300形成于所述感光元件20的所述感光面210的像分析等得到实际景物上的各个点的位置，并获得实际景物的轮廓。
参照图1，所述潜望式摄像模组100进一步包括一对焦机构60，其中所述对焦机构60能够使得实际景物对应的图像被保持于所述镜头单元30的焦距上，以提高所述潜望式摄像模组100的成像效果。优选地，所述对焦机构60被设置于所述镜头单元30，所述对焦机构60能够驱动所述镜头单元30转动而完成对焦。比如说，所述对焦机构60能够驱动所述镜头单元30沿着Z轴方向运动而实现对焦。值得一提的是，所述处理装置50能够根据实际景物的轮廓决定当前区域采用的对焦参数，将照片中出现的所有景物保持在焦距上，即，可以通过算法去补偿所述对焦机构60在对焦过程中存在部分的误差，进而降低对所述对焦机构60的精度要求，并能够保障成像的效果。
参照图1，所述潜望式摄像模组100进一步包括一防抖机构70，其中所述防抖机构70被设置于所述镜头单元30和/或所述光处理单元10，所述防抖机构70能够减小抖动对拍摄效果的影响。值得一提的是，所述潜望式摄像模组100能够让40cm至无限远范围的物体保持清晰，且在拍摄过程中对使用者手部的抖动没有自动对焦那么敏感。
在说明书附图4所示出的所述潜望式摄像模组100的这个具体的实施例中，所述潜望式摄像模组100进一步包括一辅助元件80，其中所述辅助元件80被设置于所述光处理单元10和所述镜头单元30之间，且所述辅助元件80被保持于所述感光元件20的感光路径，从所述光处理单元10射出的所述单色光300经过所述辅助元件80后被分散，使不同颜色的所述单色光300的重叠部分被减少，这样，所述红色光、所述绿色光以及所述蓝色光的重叠区域被减少，以利于所述感光元件20更好地接收对应颜色的所述单色光300，并提高了所述红色光、所述绿色光以及所述蓝色光单独形成的图像的清晰度，从而能够更准确地获取实际景物所在的位置，以得到实际景物的轮廓，并更好地呈现出立体效果。优选地，所述辅助元件80被实施为一柱面镜。优选地，所述辅助元件80被实施为一自由曲面。
说明书附图5中示出的所述潜望式摄像模组100与附图2A中示出的所述潜望式摄像模组100的差异在于，图5中示出的所述潜望式摄像模组100进一步包括一驱动元件90，其中所述光处理单元10被可驱动以转动地连接于所述驱动元件90，使得从所述光处理单元10射出的所述红色光、所述绿色光以及所述蓝色光能够全部被所述感光元件20接收，通过这样的方式，使得所述感光元件20不需要扩大所述感光元件20的所述感光面210的面积就能够接收全部的所述红色光、所述绿色光以及所述蓝色光。举例来说，由于所述光处理单元10对不同的颜色的所述单色光300的折射率不同，从所述光处理单元10射出的所述单色光300与YZ平面所成的角度不同，随着光的传播，所述单色光300之间的距离会变大，若要接收全部的所述红色光、所述绿色光以及所述蓝色光，需要的所述感光元件20的感光面积偏大，不利于所述潜望式摄像模组100轻薄化，而通过驱动所述光处理单元10绕Y轴转动，使得所述感光元件20能够依次接收所述红色光、所述绿色光以及所述蓝色光，并分别得到三种颜色的所述单色光300对应的图像，以在后续能够得到所述第一图像101。
依本发明的另一个方面，本发明进一步提供一潜望式摄像模组的图像获取方法，其中所述图像获取方法包括如下步骤：
(a)藉由一光处理单元10转折来自一被拍摄物体的一复合光400的同时分散所述复合光400，并形成多束单色光300，其中至少一束所述单色光300是一红色光，至少一束所述单色光300是一绿色光，至少一束所述单色光300是一蓝色光；
(b)藉由一感光元件20接收所述红色光、所述绿色光以及所述蓝色光；以及
(c)获取所述被拍摄物体的轮廓。
具体来说，所述光处理单元10改变了经过进入所述潜望式摄像模组100的光束的光路方向。比如说，沿着X轴方向传播的所述复合光400入射至所述光处理单元10，经过所述光处理单元10后能够沿着Z轴方向传播，即，藉由所述光处理单元10能够使得进入所述潜望式摄像模组100的光束的光路发生转折，进而所述潜望式摄像模组100在具有长焦拍摄效果的同时能够降低所述摄像模组1000的整体高度，以利于所述摄像模组1000被应用于一移动电子设备2000，并符合所述移动电子设备2000轻薄化发展的趋势。并且，在所述步骤(a)中，外部环境中的所述复合光400经过所述光处理单元10能够发生色散，进而形成不同颜色的所述单色光300，即，所述复合光400经过所述光处理单元10后发生色散形成所述红色光、一橙色光、一黄色光、所述绿色光、所述蓝色光、一靛色光以及一紫色光七种颜色的所述单色光300，并在后续，所述红色光、所述绿色光以及所述蓝色光这三种颜色的所述单色光300能够成像于所述感光元件20的一感光面210。
在所述步骤(b)中，所述感光元件对应地接收所述红色光、所述绿色光以及所述蓝色光。具体来说，藉由所述感光元件210的所述感光面210的所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113分别地接收所述红色光、所述绿色光以及所述蓝色光。更优选地，所述红色像素单元2111、所述绿色像素单元2112以及所述蓝色像素单元2113按照R-RB-RGB-RG-G的顺序自上而下地排列的方式对应地接收所述红色光、所述绿色光以及所述蓝色光。
在所述步骤(b)之前进一步包括步骤(e)：藉由一镜头单元30汇聚所述单色光300。
优选地，在所述步骤(e)之后进一步包括步骤(f)：藉由一辅助元件80扩大不同颜色的所述单色光300之间的距离。具体来说，从所述光处理单元10射出的所述单色光300经过所述辅助元件80后被分散，使不同颜色的所述单色光300的重叠部分被减少，这样，所述红色光、所述绿色光以及所述蓝色光的重叠区域被减少，以利于所述感光元件20更好地接收对应颜色的所述单色光300，并提高了所述红色光、所述绿色光以及所述蓝色光单独形成的图像的清晰度，从而能够更准确地获取实际景物所在的位置，以得到实际景物的轮廓，并更好地呈现出立体效果。
在所述步骤(b)之前进一步包括步骤(g)：藉由一滤色元件40过滤杂光。具体来说，以仅允许所述红色光、所述绿色光以及所述蓝色光通过的方式过滤杂光，保障仅所述红色光、所述绿色光以及所述蓝色光能够成像于所述感光元件20，以在后续能够根据所述红色光、所述绿色光以及所述蓝色光分别成的像分析实际景物所在的位置，并获取实际景物的轮廓。通过过滤杂光的方式保障了成像的清晰度，并减少了其他颜色的所述单色光300对获取实际景物所在位置的干扰，以利于提高所述潜望式摄像模组获取实际景物所在位置的准确性，以在后续能够更好地呈现出实际景物的轮廓。
优选地，在所述步骤(b)之前进一步包括步骤(h)：转动所述光处理单元10。具体来说，藉由一驱动元件90够驱动所述光处理单元10转动，使得所述感光元件20能够依次接收所述红色光、所述绿色光以及所述蓝色光，通过这样的方式，能够使得从所述光处理单元20射出的所述红色光、所述绿色光以及所述蓝色光能够全部被所述感光元件20接收。
在所述步骤(c)中进一步包括如下步骤：
(c.1)分别地形成所述红色光、所述绿色光以及所述蓝色光的像；
(c.2)分析所述红色光、所述绿色光以及所述蓝色光的锐利程度；以及
(c.3)确定所述被拍摄物体所在的位置。
在所述步骤(c.3)之后进一步包括步骤(c.4)：根据所述被拍摄物体的位置获取实际景物的轮廓。具体来说，所述红色光、所述绿色光以及所述蓝色光的折射率、传播速度等光学性质不一样，由实际景物上的同一个点，或是位于同一垂直平面内的点，即，与所述潜望式摄像模组的所述感光元件20的所述感光面210距离相同的点所反射进入所述潜望式摄像模组内的所述复合光400被分散形 成的所述红色光、所述绿色光以及所述蓝色光会被聚焦于不同的平面，当所述感光元件20的所述感光面210的位置固定不变时，所述感光元件20的所述感光面210接收到的不同颜色的所述单色光300的锐利程度不相同。比如说，实际景物的上的同一位置反射进入所述潜望式摄像模组的复合光400分散形成的所述红色光形成于所述感光元件20的所述感光面210的像的锐利程度大于由所述复合光400分散形成的所述蓝色光于所述感光元件20的所述感光面210的成像。同样的，由所述感光元件20的所述感光面210接收的具有相同锐利程度的不同颜色的所述单色光300对应的实际景物的上的各个点位置也会不相同。比如说，所述红色光和所述蓝色光于所述感光元件20的所述感光面210的成像具有相同的锐利程度，对应的所述红色光对应的实际景物上的点与所述潜望式摄像模组的距离大于所述蓝色光对应的实际景物上的点与所述潜望式摄像模组的距离。进而藉由所述感光元件20的所述感光面210接收所述单色光300的方式分析不同颜色的所述单色光300形成于所述感光元件20的所述感光面210的像，以得到实际景物上的各个点的位置，并获得实际景物的轮廓，从而获取实际景物的深度信息。
在所述步骤(c.4)之后进一步包括步骤(i)：根据实际景物的轮廓生成一对焦参数。进一步地，所述潜望式摄像模组根据生成的所述对焦参数完成对焦，并获得所述潜望式摄像模组100的一第一图像101。
依本发明的另一个方面，本发明进一步提供一摄像模组的图像获取方法，其中所述图像获取方法包括如下步骤：
(a)藉由至少一潜望式摄像模组100的一光处理单元10分散一复合光400，并形成多单色光300；
(b)藉由所述潜望式摄像模组100的一感光元件20接收对应的一红色光、一绿色光以及一蓝色光；
(c)获取实际景物的轮廓；以及
(d)辅助一主摄像模组200完成对焦。

在所述步骤(c)之后，进一步包括步骤(e)：藉由所述潜望式摄像模组100获得一第一图像101。
在所述步骤(d)之后，合成所述摄像模组1000的一最终图像103。具体来说，通过算法将所述第一图像101和所述第二图像102进行合成，以得到所述最终图像103，其中所述第一图像101能够具有准确的深度信息，通过所述第一图像101和所述第二图像102融合得到的所述最终图像103能够体现出实际景物的轮廓，并呈现出立体的效果，进而提高了所述摄像模组1000获取的图像的质量。举例来说，参照图7所示，使用带有所述摄像模组1000的一移动电子设备2000进行人脸拍摄时，所述摄像模组1000的所述潜望式摄像模组100获取的所述第一图像101能够体现人脸的实际存在的位置，即，构成人脸的点和点之间的相对位置，进而得到人脸的轮廓，且所述第一图像101中呈现出了人脸的深度信息，当第一图像101和所述主摄像模组100获取的所述第二图像102进一步合成所述最终图像103后，所述最终图像103能够呈现出人脸的立体轮廓。
